Abstract: A method of depositing nickel onto an object including; using a heat source 7 to heat a nickel containing electrolyte solution 3, using a pump 12 to allow the electrolyte 3 to continuously flow between the anode 4 and cathode 5, and applying direct current to the anode 4 and cathode 5 to allow nickel to deposit on the cathode 5, where the cathode 5 is the object. The object may contain one or more of aluminium, titanium, stainless steel or molybdenum, possibly covered in an oxide layer. The electrolyte 3 may be heated first before being allowed to continuously flow or flow continuously prior to heating. The electrolyte 3 may be heated to a predetermined temperature between 45 and 75 °C, before applying a current. The electrolyte 3 may also continuously flow until a thermal equilibrium is reached with the electrolyte 3, anode and cathode, prior to applying current to the anode 4 and cathode 5. The electrolyte 3 may be circulated in a turbulent flow. The anode 4 and cathode 5 or object may be spaced between 1 and 4 mm apart. A further aspect relates to a method of thickening an aluminium oxide layer on an aluminium object, using a heat source 7 to heat a nickel containing electrolyte solution 3 to a predetermined temperature and using a pump 12 to allow the electrolyte 3 to continuously flow between surfaces of an anode 4 and a cathode 5; where the cathode is an object and no current is supplied.

Title: Improvements in or relating to well abandonment and slot recovery
Inventor: MICHAEL WARDLEY
IPC: E21B29/00
Filed: 2017-05-04
Abstract: A method and apparatus for casing recovery for well abandonment and slot recovery is described. A string is run-in, the string including a hydraulic jack 18, an anchor 28, a casing spear 20, a downhole flow pulsing device 22 and a pressure drop sub 24. The casing spear grips 20 an upper end of the length of casing to be pulled. The anchor 28 is set in casing of a greater diameter above the length of cut casing. Fluid pumped through the string and through the pressure drop sub 24 will preferably linearly increase fluid pressure at the hydraulic jack 18 to a first fluid pressure. Fluid pumped through the downhole flow pulsing device will vary the fluid flow superimposing a cyclic pressure on the first pressure. Fluid at the first pressure superimposed with the cyclic pressure enters the hydraulic jack 18 and causes oscillation of an inner mandrel of the hydraulic jack 18. The jack 18 moves the oscillating inner mandrel upwards relative to the anchor 28 to pull the length of casing.
